Workflow Generation Methods, Devices and Systems, Media, and Program Products

A workflow generation apparatus comprising:

• a receiving module to receive a behavior tree construction operation performed by a user on a graphical user interface, wherein the construction operation comprises an addition operation for a behavior tree node;
• wherein the behavior tree node comprises a first iterator node, the first iterator node comprises an input end adapted to receiving a first iterative item list, and a first work link, and the first iterative item list comprises a plurality of first iterative items and an execution sequence of each first iterative item;
• a behavior tree generation module to generate, in response to the behavior tree construction operation, a behavior tree comprising the first iterator node;
• and
• a workflow generation module to parse the behavior tree to acquire a workflow, wherein the workflow indicates that each first iterative item executes the first work link based on the respective execution sequence in the first iterative item list.
